I agree that this should have and would have been included in the estimate. If they are working in that area, it would have been a pretty crappy job had they not blended the pillar. Maybe they are saying they had to go higher due to the clearcoat and they should have verified that they were going to get paid for that if it was outside of their estimate. At the same time, how much can they possibly be trying to charge you for this small amount of work compared to the big picture? That's what I'm waiting to hear. The answer should be, if the insurance company won't pay more, then they will eat the extra expense. It certainly won't be enough to hire a lawyer unless it's a relative willing to work pro bono.
